JS has no impact on OD and PA and whether it's guards or forwards 1v1 yields the same amount of HA and DR training (the only difference is that all secondary training go to JS in 1v1 guards, while it's split 50/50 between JS and IS in forwards)
I agree that JS has no impact on OD/PA. I meant to include that as having an impact on IS. I disagree that 1v1 trains the same amount of HA and DR. 1v1 guards trains more HA for bigs. 1v1 forwards trains more DR. 1v1 guards also trains a significant amount of JS reducing the need for JS training later on and allows you to focus on inside skills.
ID is pulled by IS and SB, trains ID+IS/SB secondary
IS is pulled by ID and JS, trains IS+ID/JS secondary
RB is pulled by IS and ID, trains RB+IS/ID secondary
Cross training and elastics are not the same thing.
ID is affected by IS and SB. Higher IS has a positive effect, while higher SB has a small negative effect.
IS is affected by JS, OD, ID, and RB. Higher JS, ID, and RB has a positive effect, while higher OD has a small negative effect.
RB is affected by ID and JR. Higher ID is positive and higher JR is negative.
That being said, all of this is theoretical based on data put together by BB users. So we could both be wrong.
